IMPROVEMENT IN STRAW-CUTTERS.

Specification forming part of Letters Patent No. 143,356, dated September 30,1873; application led June 2, 1873.

To all whom it may concern:

Be it known that I, AUGUST KINDERMANN, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain Improvements in Straw-Cutters, of which the following is a specification:

This invention consists in the arrangement of devices by which the straw is taken from the hopper by two feed-rollers, each having a positive motion, and delivered to the knife in a compressed state between two blocks, forming a narrow space, and in the construction of the devices, as hereinafter more fully described.

To enable others skilled in the arts to make and use my invention, I will now proceed to more definitely describe the same, reference being had to the accompanying drawing, in which- Figure l is longitudinal vertical section on line .fr x. Fig. 2 is plan view of the same with the hopper removed. Fig. 3 is a detail crosssection, showing the guideways for the knife.

In the drawing, A represents a frame of suitable construction, to which the hopper B is attached.` In this hopper is arranged a guideboard, b, upon which the straw is placed, and is held by a spring-cover, b, secured to the opposite side of the hopper by a spring, b",

double-edged and arranged in an oblique manner, so as to give a shearing cut. It is secured in a iame, G, which'slides in suitable guideways H H', that are secured to the inner side of the frame A, as will be more clearly seen in Fig. 3. The frame is provided at one end with a lug, h, to which a pitman or connecting-rod,

I, is attached, and connects it with a orankwheel, K, on a shaft, L, in suitable bearhigs on the rear end of the machine. On the eX- tended end of shaft a is secured a cone-pulley, M, which imparts motion to the pulley N 011 shaft L, by which the knife and frame are reciprocated.

Motion may be imparted to crank-wheel O by hand; or any prime motive power may be substituted, so as to operate it by horse or steam power.

The advantages of my machine are, that there is no danger in feeding the straw by hand 5 it is very simple in construction 5 the knife can be readily removed for sharpening, and the straw is cut off squarely and regularly, so thatno long pieces are left, but all are of an even length, as the knife has a shearing cut, and no long pieces can be drawn in by it.

Having thus described by invention, what I claim, and desire to secure by Letters Patent isrIzhe hopper B, provided with the guide-board b and spring-cover b, and the two toothed feedrollers C C', each having a positive motion, and the blocks E El, forming the narrow opening, all located directly above the knife F, all constructed and arranged for operation, as and for the purpose specified.
